This is a 1972 Silverface (non-master volume) Super Reverb that has been thoroughly blackfaced.  When we got it, it only had blackface cosmetics, and we finished the job by rolling back UK the circuit to the classic AB763 blackface circuit.  It now sounds exactly like the ultra-desirable earlier 60s models.  All the hardware, including the original CTS speakers date from 1972.  We have, however, installed a UK transformer so you can run it without an additional stepdown transformer.   A great way to get a classic at an affordable price.
